Invention mechanism：
In organic compound, the angle between two chemical bonds that the same atom of intramolecular is formed is known as bond angle, and bond angle is logical The common number of degrees indicate that the electronegativity of central atom and coordination atom, can influence the bond angle of molecule in organic compound molecule.When with Central atom bonding coordination atom electronegativity increase when, coordination atom electron-withdrawing ability enhancing, bond electron pair will to The movement of position body direction farther out from central atom makes between key pair because that repulsion reduces is close to each other, so that bond angle also reduces therewith, On the contrary, when the electronegativity for the coordination atom being bonded with central atom reduces, the enhancing of coordination atom electron donation, bonding electrons To will be moved to central atom direction, from central atom closer to making to be located remotely from each other because repulsion increases between key pair, to bond angle Increase therewith.
According to Pauling Electronegativities, the electronegativity of C, H and O atom is respectively 2.55,2.20 and 3.44, and according to Valence electron balancing energy is theoretical, and the calculation formula of Group Electronegativity is shown below：
In formula, xiFor the electronegativity of i atoms neutral atom before bonding, Nve,iFor valence electron number in i atoms, niFor i The number of atom in the molecule.Calculating step for more complex Group Electronegativity is mainly：Simple group is calculated first Electronegativity, then regard simple group as electronegativity that quasiatom calculates more complex group again, such successive iteration, finally Obtain the electronegativity of Targeting groups.It should be noted that when calculating the electronegativity of quasiatom, base (for example, group- Base of OH is O atom) in the valence electron of non-bonding regard the valence electron of quasiatom as.
C atoms can be with the O atom of hydroxyl in dihydric alcohol after the C-O keys fracture of carboxyl in terephthalic acid (TPA) in the present invention In conjunction with the new C-O keys formed in ester group, the C atoms key C-C formed with C atoms on phenyl ring in ester group and the chemistry newly formed Bond angle between key C-O is denoted as α, and the change of bond angle α can influence annulation, and when α is less than 109 °, molecule is easy to cyclization, and With the increase of α, the probability of molecule cyclization can decline.Present invention introduces branched dihydric alcohol, structural formula is shown below：
In formula, R1And R2It is each independently selected from the straight-chain alkyl-sub that carbon atom number is 1~3, R3It is 1 selected from carbon atom number ~5 alkyl, R4The alkyl for being 2~5 selected from carbon atom number.The diol structure due to introducing branched structure and backbone, The electronegativity of its alkoxy portion can be made to weaken, can also be obtained in the diol structure with two by the calculation formula of Group Electronegativity The electronegativity of the connected group of carbonyl is between 2.59~2.79 in acid, and the group-being connected with carbonyl in diacid in ethylene glycol OCH2CH2Electronegativity be 3.04, thus its alkoxy is than-the OCH in ethylene glycol2CH2There is stronger electron, because This makes the bond electron pair on the chemical bond C-O keys newly formed that will be moved to center C atomic orientations, from central atom closer to, Make to be located remotely from each other because repulsion increases between key pair, so that bond angle α is more than 109 °, the probability for generating linear polymer increases, To reduce the generation of cyclic oligomer, this is conducive to eliminate fracture of wire and phenomena such as uneven thickness, advantageously reduces oligomer The influence that the mechanical properties such as fracture strength and elongation at break to fiber generate, to improve product quality.
The oil agent of the present invention is that a kind of viscosity is low, heat resistance is good and the higher finish of film strength.In the prior art The viscosity of finish is higher mainly due to containing conventional polyester class compound or polyether compound in finish, such compound by In molecular weight is larger and the effect of hydrogen bond, intermolecular effect is larger to show as that kinematic viscosity is larger, thus causes finish Viscosity is higher, and the viscosity of finish can significantly reduce after addition crown ether, mainly since crown ether oneself viscosity is relatively low and is pearl Small molecule, crown ether can be preferably compatible in polyesters compound or polyethers finish system, while enter polyesters compound Or between polyether compound strand, the active force between strand is shielded, to reduce the viscosity of finish system.Existing skill The film strength of finish is relatively low mainly since the antistatic agent of preparation medium is mostly containing metal ion or with salt in art Form exists, and causes antistatic agent and the poor compatibility of polyesters compound or polyethers in finish, crown ether that can improve oil film Intensity can generate salting in effect after being mainly added due to crown ether, improve antistatic agent and polyesters compound or polyethers Compatibility, and then improve finish oil film strength.In addition, crown ether has higher volatilization point and excellent Heat-resistant stable Property, the heat resistance of finish introduced after crown ether is also obviously improved, and the present invention uses finish containing crown ether, due to crown ether With lower viscosity, higher volatilization point, smaller finish friction coefficient and excellent heat-resistant stability, to improve The processing performance of fiber.
